Taking Jiangling depression in Jianghan saline basin as an example,following issues are analyzed in this article such as the characters of chief source rock,the amount of hydrocarbon generation and expulsion of the source rock,the primary times of hydrocarbon generation and expulsion of the source rock,and oil & gas resource potential by using the methods of basin modeling.

Diagenesis of anhedritite in the Cretaceous reservoir and its influence on the hydrocarbon distribution in southeast Jianghan Basin;

Exploration potential contrast of non-sandstone reservoirs within salt-layers between Shashi and Qianjiang Formations,Jianghan Basin;

Characteristics of pore structures and oil production potential of sandstone reservoir of Paleogene Xingouzui Formation in Jianghan Basin;

Based on the distribution characteristics of proven oil field reserves size and the changing trend of oil yield and discovery rate per exploration well over the years in the Qianjiang Sag,the Jianghan Basin,three different kinds of statistic methods such as pool size sequence,Weng's life cycle and exploration benefit method have been chosen in the paper.

Nonsandstone reservoirs between salt beds of Qianjiang Formation in the Qianjiang Sag of the Jianghan Basin are mainly composed of dolomicrite,glauberite rock,mudstone and their peperite.

The bulk rock analysis technology of organic petrology was used in this paper to systematically study the maceral composition, hydrocarbon generating components and organic thermal evolution of the Lower Tertiary source rock in the Jianghan Basin.

According to the special geologic and seismic circumstances of Jianghan saline lake basin, the integrated exploration methods were developed, which including building the geologic models of saline lake basin by the high accuracy sequence stratigraphy, predicting reservoir beds according to the impedence and gamma inversion results.

The sequence stratigraphy feature of intersalt sediments is the special rock in Qianjiang saline lake basin, which isn't simple sediments and has major changes in component and texture with basin area and geologic age.

Classification and Significance of Reservoir-forming Dynamic System in Salt Lake Basin
